Traditional methods based on trackside infrastructure or satellite signals often suffer from limited precision or high cost, especially in Global Navigation Satellite Systems (GNSS)-denied environments. To address these challenges, this article proposes a hybrid vision–inertial train positioning method that combines the visual absolute positioning with inertial measurement unit (IMU)-based relative positioning. An enhanced you only look once (YOLO)-based object detection algorithm and an end-to-end text recognition network are employed to identify and interpret railway landmarks. The absolute position of the train is then retrieved by matching recognized text with a preconstructed database. To achieve continuous and robust localization, a differential evolution Kalman filter (DE-KF) is introduced to adaptively fuse IMU data with the vision-derived observations, dynamically tuning the process noise covariance in response to environmental variation. The proposed method was validated at Beijing National Railway Experimental Center. Experimental results demonstrate that the system maintains positioning errors within 3.5 m and achieves high recognition performance, with an mAP50 of 98.0%. These findings confirm the effectiveness of the proposed fusion framework for real-time, accurate, and resource-efficient train localization.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 18","pages":"35323-35334"},"PeriodicalIF":4.3,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To ensure safe and efficient operation, these cables need to exhibit strong resistance to partial discharge (PD) and arcing, which are critical factors affecting insulation integrity. Among the various multilayer multifunctional electrical insulation (MMEI) structures developed, the ARC-SC-T-MMEI described in this article has been selected for further investigation due to its multifunctional properties. We examine the PD behavior of the fabricated flat samples under atmospheric and low-pressure conditions to evaluate the impact of environmental variations on electrical performance. A comparative analysis of the PD characteristics is conducted using the Pearson correlation coefficient, which provides insights into how pressure influences discharge activity. The dielectric strength of the samples is assessed under both ac and dc voltage to evaluate their withstand capability and breakdown characteristics. A two-parameter Weibull distribution was employed for statistical comparison. In addition, we fabricate a cable prototype using the optimized MMEI system, analyzing its PD behavior and dielectric strength under ac and dc conditions at both atmospheric and low-pressure settings. These findings highlight the effectiveness of MMEI insulation in mitigating PD and enhancing dielectric strength, thereby advancing MVdc cable technology for electric aircraft applications.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 9","pages":"2401-2409"},"PeriodicalIF":1.5,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145061967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, we incorporated a Boltzmann term to analyze the transition of discharge modes. The results indicate that iterative updates to the parameters of external circuit components can substantially diminish the reflection coefficient and find the optimal matching parameters. Comparison of operations with and without the activated matching network illustrates that plasma discharge is significantly enhanced with the matching network engaged, accompanied by a notable reduction in the time required to attain steady state.

Node localization technology is fundamental to the operation of these applications. Because traditional received signal strength indicator (RSSI) fingerprint matching localization algorithms face significant challenges in practical applications, such as low positioning accuracy and high computational complexity, this article proposes an optimized method for RSSI-based fingerprint matching localization in WSNs, which enhances effectiveness and expands application scope. First, Kalman filtering is applied to preprocess RSSI values, reducing noise interference. Second, the RSSI distance model is used to construct fingerprint node circles, forming a fingerprint database and lessening the data required for matching. Finally, dynamic time warping (DTW) distance measures the similarity between positioning points and fingerprint data nodes, significantly enhancing the accuracy and precision of the matching process. In addition, the optimized algorithm also supports collaborative localization between multiple agents, so as to achieve real-time tracking and positioning of objects in space. The simulation and experimental results indicate that the algorithm delivers remarkable performance in 2-D and 3-D localization, with a 93% improvement in positioning accuracy and a nearly tenfold boost in computational efficiency.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 18","pages":"35524-35533"},"PeriodicalIF":4.3,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The voltage–current waveforms and discharge images were employed to systematically investigate the differences in discharge initiation, spatial morphology, and temporal evolution under the two excitation modes. The results show that nanosecond-pulsed SDBD exhibits reverse discharge during the voltage fall phase, whereas ac-driven SDBD exhibits an earlier discharge onset due to cumulative surface charge effects. As the voltage amplitude increases, both excitation modes produce more streamer channels and broader discharge areas. However, their discharge distribution modes differ significantly. Annular SDBD under ac excitation produces filamentary discharge localized along the edge of the high-voltage electrode, whereas under nanosecond pulse excitation, the separated-channel discharge channels are produced. These differences are attributed to variations in voltage rise time and surface charge dynamics. Nanosecond pulses create a stronger transient electric field, expanding discharge coverage. In ac-SDBD, residual electrons near the high-voltage electrode promote early breakdown in the next cycle. In contrast, reverse discharge under pulsed excitation reduces residual positive charge and delays the next discharge. Nevertheless, the high conductivity of established channels promotes repeated breakdown in the same location, maintaining separated-channel distribution.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 9","pages":"2168-2176"},"PeriodicalIF":1.5,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review summarizes the current research on the combination of CAP and RT, focusing on its radiosensitizing effect, the ability to repair radiation-induced injury, and the challenges and solutions in the clinical application and promotion of this direction. Reactive oxygen and nitrogen species (RONS) produced by CAP increase the sensitivity of tumor cells to radiation and reduce the damage of radiation to normal cells, thus improving the effects and safety of RT. In addition, CAP has been proven to promote the repair of radiation-induced skin damage, especially radiation dermatitis (RDs), a common side effect of RT that currently lacks effective treatment options. By alleviating RD and enhancing tissue regeneration, CAP provides a new treatment method for managing the adverse reactions of RT. Although it has broad prospects, some challenges hinder the wide application of CAP in clinical settings, including limited penetration depth, the lack of standardized dosimetry, and the intricate nature of its underlying molecular mechanisms. In addition, the standardization of CAP equipment, precise parameter control strategies, and long-term safety issues require further investigation. This review emphasizes the necessity of continuous exploration to improve the role of CAP in RT and provides insights for the development of more effective and safer cancer treatment methods.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 9","pages":"2477-2490"},"PeriodicalIF":1.5,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145061973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed fractal SSPPs unit has a lower cutoff frequency than the conventional rectangular SSPPs unit, even with the same periodic unit size. Due to the compact fractal SSPPs structure, the limitation of the lower cutoff frequency of the SSPPs-based TL combining with microstrip-to-slotline transition (MST) structure is able to be eliminated, making the frequency range of the designed TL more flexible. Also, by optimizing the coverage of the MST structure and SSPPs structure, the commonly used transition SSPPs portions for momentum matching can be removed; thus, the circuit size is further reduced greatly. Finally, by cooperating the high-pass response of the adopted MST structure and the natural low-pass property of the proposed fractal SSPPs, a bandpass TL with the controllable upper and lower cutoff frequencies is realized. Moreover, by rationally designing the MST structure, the high-order modes of SSPPs are suppressed, leading to a broad upper stopband. The well-designed bandpass TL is fabricated and measured. The experimental and simulation results are in excellent agreement, effectively validating the proposed structure and design method. The size of the fabricated TL is <inline-formula> <tex-math>$0.43lambda _{mathrm {g}} times 0.32lambda _{mathrm {g}}$ </tex-math></inline-formula>, indicating the advantage of miniaturization and can be well used in communication systems.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"53 9","pages":"2234-2240"},"PeriodicalIF":1.5,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
